Here's a DSDT for EVGA X58 SLI3 Mobo

I had a very hard time finding a premade DSDT for this mobo so I figured I'd share! If this isn't the proper place for such things please let me know and I'll move it.

Obviously I can't guarantee your own results, but I made this DSDT from scratch by extracting this board's file and editing it with DSDTSE. So far it seems to be working perfectly on my own EVGA X58 SLI3 board after about 2 months of use. The only issue I've encountered is that the sound in System Prefs needs to be set to "Internal Speakers" to work but it functions perfectly. This quirk may or may not be related to the DSDT file so, again, your results may vary.

O.M.G. thanks so much! I will give it a try and see how it goes.
Did you get sleep working ok?
Also, which BIOS version are you using?
Thanks again!
I gave it a go but unfortunately it kernel panicked in AppleIntelCPUPowerManagement.
I had BIOS 76, then flashed back to 43 since this is meant to be the good version. I enabled speedstep and C1E but no cigar :(
Btw I have an E760 classified maybe you have an E761 thats why it doesnt work?
